Re: [xml] Strange validation errors in libxml 2.9.0 with MSVC 2010
Hi, thanks for checking in. As far as I know, there is no solution for this problem yet. Daniel recommended to debug into xmllib to find out what the problem might be - I simply don't have the bandwidth to do that. So, I opted for avoiding the problem as a whole by downgrading to 2.8.0. I guess this makes the fix more urgent - it's a bit harded to downgrade Ubuntu deployments. Is this happening on a 32bit distribution, 64bit or both?

Hi, not a lot of help I know, but this is all I have to offer right noww. I think, Ubuntu does upgrades pretty well. I have upgraded from 9.x to 12.x each release (have not tried 13.x yet) and I had only one minor problem (with grub), so I'd like to think you can rule out the upgrade issue. But, yes, do give it a try if you have the time - you never know. It's the ghost in the machine :-) Best regards: Zoltán Ördögh On Sun, Apr 28, 2013 at 1:32 PM, brezhoneg1 brezhon...@yahoo.fr wrote: Hi thanks a lot for your response So far, it occurs on a Ubuntu13.04 32-bits (an upgrade from Ubuntu12.10 which already was an upgrade from Ubuntu12.04). These two upgrades went without problems, but maybe a clean installation from scratch would be better to avoid risks of silent misfunctioning due to a bad cleanup of a previous version. For 64 bits, I don't know yet (not tested), but I guess this bug is likely to be on all platforms, since you've got it on Windows too. Anyway, the programs run very well, except they emit hundreds of irrelevant error messages that will surely scare end users for nothing ! Best Regards E.

Re: [xml] Strange validation errors in libxml 2.9.0 with MSVC 2010
Hi Csaba, thank you for checking! xmllint works flawlessly in 2.9.0 here as well - as I have indicated in the original email. As a quick recap: - I use pretty much the same code to read the XML using XMLReader as xmllint: xmlReaderForFile(...) followed by an xmlTextReaderRead (...) - For the exact same documents and source code: - libxml 2.9.0 gives a validation errors on MSVC 2010 (the validation error appears for every single attribute and element). - libxml 2.8.0 and below works perfectly. - My conclusion: a bug has been introduced in 2.9.0 that prevents validation on MSVC 2010.

Does it work if you change your DOCTYPE to !DOCTYPE XMLTestMe SYSTEM testme.dtd ? Hi John, thanks for the reply. I am not sure why'd you use that command line though; the file:/// prefix is not needed when you use it from the shell. I said that I believed that a relative path in a file: URL was invalid. My command line showed that Windows would not launch the file with the attempted relative path file:///./testme.xml, but it worked when I specified the absolute path file:///c:/temp/testme/testme.xml. By now I amsure that you have seen that Danniel also says that relative paths are illegal, although that does not tell you why xmllint accepts it but your program does not.

static void streamFile(char *filename) {
xmlTextReaderPtr reader;
int ret;
reader = xmlReaderForFile(filename, NULL, options);
if (reader != NULL) {

xmlTextReaderSetParserProp(reader, XML_PARSER_VALIDATE, 1);
else
xmlTextReaderSetParserProp(reader, XML_PARSER_LOADDTD, 1);
/*

if ((timing) (!repeat)) {
startTimer();
}
ret = xmlTextReaderRead(reader);
while (ret == 1) {
if ((debug)

processNode(reader);
ret = xmlTextReaderRead(reader);
}
if ((timing) (!repeat)) {
if (valid)
endTimer(Parsing and validating);
else
endTimer(Parsing);
}
if (valid) {
if (xmlTextReaderIsValid(reader) != 1) {
xmlGenericError(xmlGenericErrorContext,

progresult = XMLLINT_ERR_VALID;
}
}
/*

xmlFreeTextReader(reader);
if (ret != 0) {
fprintf(stderr, %s : failed to parse\n, filename);
progresult = XMLLINT_ERR_UNCLASS;
}
} else {
fprintf(stderr, Unable to open %s\n, filename);
progresult = XMLLINT_ERR_UNCLASS;
}
}
I tried using the exact same code but I still get the same validation
errors on the first call to xmlTextReaderRead...
It is vexing me...
Any thoughts?
Thank you!

Hi all,
I've been using libxml 2.7.7 in the past with BCB6 and it was working fine.
Now I use libxml 2.9.0 with MSVC 2010 (_MSC_VER = 1600) and I get strange
validation errors when I try to read the file back that I wrote out before.
I am getting a bit frustrated because I am using the exact same code as I
did in BCB6 and despite all my efforts, it always fails.
When I validate the XML with a third-party tool, it all checks out just
fine.
When I run: xmllint.exe --valid testme.xml, it simply dumps the XML
back without any validation errors.
For some reason, libxml 2.9.0 on MSVC 2010 won't validate it (even though
it's from the same build as xmllint.exe itself).
This is the code that opens the file:
#include libxml/xmlreader.h
.
.
.
m_pxmlTextReader=xmlReaderForFile(sXML.c_str(), NULL, XML_PARSE_COMPACT |
XML_PARSE_BIG_LINES | XML_PARSE_DTDVALID);
if(m_pxmlTextReader)
{
if(xmlTextReaderRead(m_pxmlTextReader)==1
xmlTextReaderIsValid(m_pxmlTextReader)==1)
{
// processing
}
...
// processing is never reached due to the validation errors.
I attached a simple XML with the DTD that can be used to test it in case
you're willing to give it a go.
I captured the errors I see in output.txt, please find it attached.
As you can see from the output, the DTD is found but for some reason,
libxml can't match it vs. the XML file.
I don't think it's relevant but this is the libxml config that I use at
the moment:
